Cutting of a pine tree - experimental garden #2
Day 1:  I followed instructions on this web page
Taking a branch from my pine tree - not too large and planted it following the earth layering etc

It will take 15 yrs for it to grow into any tree - for now, a bonsai tree is gd, easier to control water, heat etc.

Now, can we put a pine tree indoor or it should stay outdoor?
More research.
